THE SOYBEAN YIELD FORMATION IN THE PEDOCLIMATIC CONDITIONS FROM THE HILLY AREA OF THE TRANSYLVANIA PLAIN

Abstract

Soybean yield is determined by the interaction between genetic potential and environmental factors from the specific area, maturity group of the cultivar, plants height, disease and pest tolerance, culture technology, the type of soil its pH and fertility, etc. From the most important elements that compete for the formation of the crop we mention, plants height, the number of pods per plant, the number of grains in the pod, weight of grains per plant and the mass of a thousand kernels weights (TKW). Experience established at ARDS Turda, during 2020-2022, had as its main objective the study of the influence of technological factors (tillage systems) and pedoclimatic effects on some morpho-productive characters in soybeans. Climatic conditions during the experiment period, especially in the summer, they had a significant influence (positive or negative) on the studied elements. Between the two tillage systems (plow CS and chisel MTC) no significant differences were recorded regarding for most of the analyzed elements, except for the number of grains/plant (CS 87.9 și MTC 95.8).
